Yes, I use a S2S Thermolite Reactor 8C. It seems to perform well and I used it instead of a sleeping bag at my inlaws on NSW south coast just last week. I did used an additional lite cover by morning but for most of the night, it was more than enough by itself. I have used it combined with a Roman palm 0C bag and thermals and been comfortable down to -8C. Amazing because those bags are notoriously overrated, having no discernible loft at all.
